The Inner City is situated on the east bank of the river Danube. Until 1949 it was the 4th district of the town. Since then it has largely comprised the 5th district and the 6th district. The border of the city from the east follows the line of the old city walls, which is the Small Boulevard; its sections are Károly körút (Charles Boulevard), Múzeum körút (Museum Boulevard) and Vámház körút (Vámház Boulevard). The border from the west is the river Danube itself.
A colloquial definition of inner city (or city centre, both with lower case letters) also exists according to which the city centre of Budapest, in a broader sense, is bordered by the Grand Boulevard on Pest side of the city. In Buda (if it is also included), it is bordered by the continuation of Grand Boulevard by Margit körút (Margaret Boulevard), Krisztina körút (Christina Boulevard), Budaörsi út (Budaörsi Street) and Bocskai út (Bocskai Street).[1] So the wider area comprises the whole 5th district and some parts of the 6th, 7th, 8th, 9th, and the 13th districts on the Pest side, while also certain parts of the 1st., 2nd, 11th, and the 12th. districts on the Buda side.
